Austin Road Landfill E*sion Project 0 ENVIRONMENTAL IMPACT MITIGATION MEASURE LEVEL OF SIGNIFICANCE AFTER MITIGATION G. AIR QUALITY G.1 Landfill equipment and earth moving (a)Water the working face,excavation LS activities on-site would generate fugitive area,storage pile,unpaved roads,and all dust. (SIGNIFICANT) unvegetated soil areas frequently,adding a dust palliative(a non-toxic chemical suppressant,such as magnesium chloride (MgC12)that attracts water molecules from the air),thereby keeping the surface wet for a longer period. Regarding the watering of the working face,a balance must be made between dust control and the generation of additional leachate. The landfill operator shall monitor dust levels and levels of leachate generated to determine when and where water should be applied. (b)The project sponsor shall seek to minimize the extent of areas exposed to wind erosion. Exposed surfaces, including stockpiles and other bulk materials with the potential to emit dust shall be stabilized with the application of water, chemicals,covered,or vegetated to the extent possible in accordance with the SJVUAPCD's Regulation 8030. On windy days,when dust plumes are present, active faces shall be watered down. (c)Plan and phase construction and closure operations such that they do not take place simultaneously on dry windy days. Schedule dusty activities on separate days. (d)Design the site filling plan to facilitate screening of the active face from prevailing winds,whenever possible,to minimize the amount of wind blown dust released from the working face. (e)Haul trucks carrying airborne material shall be covered during transport and sprayed with water prior to dumping if it is shown that this would reduce dust emissions A..-:-- 22 urin 22
